I) at Hollywood Park in her last start.Racing for Peter Vegso, Splendid Blended became the first 3-year-old to win the Vanity since It's in the Air won in 1979. Splendid Blended beat top racemare Island Fashion by a head in the 1 1/8-mile race. In her only other start this year, Splendid Blended ran a close fourth in the Acorn Stakes (gr. I).As a 2-year-old, Splendid Blended won or placed in all four starts. She won three races, including the Hollywood Starlet Stakes (gr. I), and ran second to subsequent champion Sweet Catomine in the Oak Leaf Stakes (gr. II) at Oak Tree. She retired with four wins from six starts and earnings of $519,900.Bred by Harry T.
